Installation of MICC Cables

MICC Power cable is a high conductivity copper conductor embedded in highly compacted magnesium oxide insulation with a robust, ductile copper sheath. MICC Cables are mainly installed in Substations for electrical lighting and small power systems.

Laying of MICC Cable

a. All cables will be laid as per approved shop drawings. Instrument and control cables will not be grouped with power cables.
b. Minimum bending radius of the cable will be checked prior to cable pulling to avoid exceeding the bending limit.
c. Cable identification tag will be made available for cable in advance and also after glanding.
d. It will be ensured that the cable ladder/cable trays are free from any sharp edges and are having sufficient spaces for installation.
e. Visual inspections are performed to ensure there are no sharp edges or burrs that could damage the MICC cables during installation.
f. Before removing the hoist, the direction of the arrow on the drum will be checked and will be in the same direction as the pull.
g. The necessary cable roller will be placed in the cable passage and the cable winch and pulling grips will be connected to the cable.
h. Proper coordination and communication between the workforce will be ensured.
i. When unrolling cable, a plastic or plywood sheet will be provided and laid in-ground for cable protection and will avoid any scratches and damages to the cable’s outer sheath insulation.
j. Cable roller guides will be placed under the cable during pulling over longer distances and standoff rollers for acute bends and will ensure that the cable is pulled with minimum effort and cable outer jacket is free at scouring lines
k. It will be ensured that the cable will not be allowed to twist or rotate about its longitudinal axis during the pulling process.
l. It will be ensured that the cable will not be bent during installation, either permanently or temporarily to a radius less than the allowed minimum bending radius allowed by the manufacturer.
m. The cables will be spaced in accordance with the approved shop drawings and tied to the ladder/tray using approved cleats and or cable ties for both horizontal and vertical run. MICC cables shall be installed on cable trays and secured to backstraps fixed to the side of the trench. Such cables shall be saddled to this cable tray at intervals of not more than 500mm as per project specifications.
n. Cables will be installed from terminal point to terminal point and straight through joints will not be made unless approved. Where a run of MICC cable is of a length that exceeds the maximum which can be manufactured, a through joint of a pattern agreed with the Engineer will be permitted as per requirements.

Installation of MICC Cables in Substations

a. Before the start of works, it will be ensured that the civil works are completed.
b. It will be ensured that all accessories, tools, and equipment are available before the start of work.
c. All the responsible precautions to prevent damage to the cable from severe blows with sharp instruments and pulling over sharp objects are taken.
d. The cable will not be pulled around corners that have sharp edges, such as corners in cable trays, or other obstructions.
e. The cables will be completely uncoiled (if needed) or removed from the reel and laid out in a straight run with the end to be pulled closest to the entry point into the support system.
f. The cable will be pulled by hand through the desired routing.
g. When changing the direction from a horizontal to a vertical pull, sheaves or pulleys will be used to guide the cable around the bend.
h. The surface run cables will be fixed with saddles at intervals of not more than 500mm as per project specification.
i. Conduct an insulation test on the cable and record the result.
j. Cable will be identified at both ends for proper identification of cable. The marker sign will be the same as the feeder designation in the cable schedule.
k. Where cable passes through a fire barrier approved fire-stopping material will be provided as recommended by the Engineer.

Termination of MICC Cable:

a. Cable glands will be brass compression glands and comply with the relevant part of BS 6121, except for MICC cables, which shall comply with BS 6207 Part 2.
b. Cut the cable off the square. This will be done with a small hacksaw, a ringing tool, or sharp cable shears.
c. Start the stripped cable by turning the joistripper clockwise down the cable.
d. When the cable is stripped to the desired length, lightly grip the cable with the pliers. Run the joistripper up to the pliers. This will give a nice clean square cut.
e. Put the gland top, olive, and gland bottom of the cable. Do not tighten it up yet.
f. Screw the pot in the cable until the sheath of the cable is flush with the bottom of the pot. Be very careful not to twist the cable while screwing on the pot. Then pull the wires slightly apart and test the wires with an insulation tester.
g. Slightly overfill the pot with potting compound. It is ensured not to touch the compound which could cause the pot not properly insulated the pot.
h. Slide the pot seal into place, making sure the wires are not twisted.
i. Insert the pot assembly into the pot crimper, it will be ensured that three prongs of crimper are between where the wires come through the seal.
j. Crimp the pot.
k. Sleeve the wire into stub sleeving and carry out another insulation test to ensure cables are free of fault. Also need to do the continuity test.
l. Slide the gland into place.
m. It will be ensured that the technicians wash their hands after the installation. Magnesium oxide is not good for health.
n. After the cable ends are terminated with the permanent seal, the cable should be subjected to IR (Insulation Resistance) Test.
